Patrick Möller has been writing about folding bikes from his shop in Prenzlauer Berg since 2009, and the Boxbike blog is one of the most practically useful and editorially honest Brompton resources in the German language. Patrick writes about new models and special editions with the eye of someone who sells and repairs these bikes every day — no manufacturer spin, no affiliate fluff, just genuine assessment from a dealer who has seen every Brompton variant come through his workshop. The blog also covers broader topics: Brexit and its impact on Brompton pricing in Germany, the folding bike community in Berlin, and occasional longer pieces about cycling culture. A rare combination of insider knowledge and genuine writing craft.
